Expand Backpack Space PS3

Ok guys, i know a way to edit PS3 game saves. NO i will not be telling anyone how. it will get patch

Ive been looking around to find a way to get extra backpack spaces. So far i have tried:

Backpack SDU code and placing in the Bank and Backpack
Setting the black market upgrades back to 0 and rinse and repeat

And neither of them work. Well the blackmarket one did but it was temporary. So when i quit it reset back to the normal 27 slots. So any ideas??

Remember im on PS3 so not bypasses. And im using Gibbed to edit my saves

Really... you start off a request like that. I know how to mod the pS3 but im not gonna tell but give me help? The bruteforce app has been out for a while.. You telling people that potentially really want to know here aint gonna change anything.... your not that popular.
Holding back data in this scene is going the wrong way

heres how to mod the PS3 saves!!
google "bruteforce save data" it’s a program that decrypts ps3 files
download revision 138 of gibbs save editor.
Load up bruteforce and use it to open up your save file there’s gonna be a box in the lower left of the program click the one that says .sav and highlight it then click the decrypt button
go to the save editor and open the save file up be sure to change the file type to ps3 in the bottom right hand box after hitting open to open it.
Then edit whatever you want and click save before you close the editor then go back to bruteforce click the .sav to highlight it then click encrypt and put the file back on your flash drive and your good to go.

Enjoy

P.S.
Yes I know a way to edit the backpack size but im not saying cause they will patch it... Good luck
